High-frequency module, filter device, and communication device

A high-frequency module, comprising:

• a mounting substrate having a first main surface and a second main surface opposite to each other;
• a first filter comprising a first substrate and having a first pass band that comprises at least a part of a first band;
• a second filter comprising a second substrate and having a second pass band that comprises at least a part of a second band;
• a third filter comprising a third substrate and having a third pass band that comprises at least a part of a third band;
• a switch configured to exclusively connect the third filter to an antenna terminal or both the first filter and second filter to the antenna terminal;
• a plurality of filters mounted on the first main surface of the mounting substrate, the plurality of filters comprising the first filter, the second filter, and the third filter;
• and
• wherein the first filter and the second filter are configured to operate in simultaneous communication with each other,
• wherein the third filter is not configured to operate in simultaneous communication together with the first filter and the second filter,
• wherein the first filter, the second filter, and the third filter are mounted on the first main surface of the mounting substrate,
• wherein the first substrate of the first filter, the second substrate of the second filter, and the third substrate of the third filter are common to each other,
• wherein the switch is mounted on the second main surface of the mounting substrate,
• wherein a filter of the plurality of filters included most in combinations of filters used in simultaneous communication is a most combined filter,
• wherein in the plan view, the most combined filter is closest to the switch among the plurality of filters, and
• wherein in a plan view of the mounting substrate, the third filter is between the first filter and the second filter.
